HEATER.

Specification of Letters Patent.

Patented Feb. 28, 1909.

Application filed August 10, 1908. Serial No. 447,855.

To all whom it may concern:

Be it known that I, EDWARD B. RAYMOND, a citizen of the United States,residing at Blackwell, in the county of Kay and State of Oklahoma, haveinvented a new and useful Heater, of which the following is aspecification.

This invention relates to heaters, the same being particularly designedfor use within breeders.

The object of the invention is to provide a heater, the burner of whichis located outside of the brooder so that danger of fire is greatlyreduced.

Another object is to provide a heater having means whereby vitiated airmay be conveyed from the floor of the breeder and to the heater anddischarged from the heater with the waste products of combustion.

Another object is to provide means whereby heated fresh air may besupplied to the interior of the breeder to displace the ex- A haustedvitiated air.

With these and other objects in view the invention consists of certainnovel features of construction and combinations of parts which will behereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings: Figure 1 is a section through a portion of a brooderhaving connected thereto a heater embodying the present improvements,the return conduit of the heater being shown in section. Fig. 2 is avertical transverse section through the heater. Fig. 3 is a plan viewthereof on a reduced scale.

Referring to the figures by characters of reference, 1 designates aheating drum closed at the top and having an opening 2 in the bottomthereof in which is fitted a chimney 3 engaging and supporting burner 4of a lamp 5 so that the products of combustion are free to flow throughsaid chimney and into the drum. Said drum is preferably formed withdiverging outlet pipes 6 which extend any desired distance in anypreferred direction and open into an outlet pipe 7 having a chimney 8extending therefrom. The drum 1 is surrounded by an inner downwardlytapered acket 9 and an outer cylindrical jacket 10. Jacket 9 forms anair compartment 11 which is closed both at the top and the bottom butopenings 12 are formed within the jacket 9 adjacent the lower endthereof and below the lower end of the jacket 10. Said jacket forms anair co1npartment 13 therein closed at its ends but having outletopenings 14 near its upper end. An air inlet ipe 15 opens into the acket10 and the out et pipes 6 are provided with slots 16 whereby air is freeto pass from the compartment 11 into the pipes 6.

When the heater herein described is in a brooder A, a circular opening Bis formed in the floor of the breeder, the diameter of said openingbeing greater than the diameter of the lower end of jacket 9 but lessthan the diameter of the corresponding end of jacket 10. It will beapparent therefore that the lower end of the outer jacket 10 will restupon the floor while the lower portion of the inner jacket will extendinto the opening B. If preferred, an annular flange 17 may be formedabout the lower end of the jacket 10 so as to rest upon the floor of thebreeder. An outlet opening O is formed in the floor of the brooderpreferably adjacent the center thereof, and secured. under the floor isa trough or conduit 18 preferably formed of sheet metal and having aflat extension. 19 extending under the acket 9 and apertured as at 20 toreceive the chimney 3. It will be apparent therefore that air enteringthe opening C will be directed within conduit 18 to the opening B.

It is thought that the operation of this heater will be clearly apparentfrom the foregoing description when readin-connection with theaccompanying drawings. When the lamp is lighted the roducts ofcombustion will pass into the rum 1 and thence outward through pipes 6and 7 to the chimney 8 which extends through the top of the brooder. Theair contained within the compartments 11 and 13 will of course be heatedand a circulation established. Fresh air will be drawn into thecompartment 13 through pipe 15 and will when heated rise and flowthrough the openings 14 into the upper portion of the brooder. As thisair becomes vitiated it will settle toward the floor and pass outwardthrough opening O and trough 18 to the opening 13 where it will enterthe apertures 12 and thus pass into compartment 11. It will then escapethrough slot 16 to the ipe 6 and thus be conveyed with the proc uets ofcombustion to the chimney 8. It will be seen therefore that the interiorof the brooder is kept constantly supplied with warmed fresh air and thevitated air therein is frequently drawn off so that there is no dangerof the chicks becoming asphyxiated. Moreover, by extending the conduit18 under the floor said floor is kept warmed and sickness among thechicks consequently reduced. Although the trough 18 has been shownextending under only a part of the floor it is to be understood that, ifpreferred, it can be enlarged so as to extend under all portions of thefloor. While the heater is particularly designed for use in brooders itis to be understood that it is also useful in incubators and in variousother structures.

What is claimed is:

l. The combination with a compartment having an outlet opening in thefloor thereof of a heater arranged within said compartment andcomprising a heating drum, noncommunicating air-distributing and airreceiving compartments surrounding the drum, said receiving compartmenthaving inlets at its lower end for receiving vitiated air from theoutlet opening in the floor of the compartment, an outlet pipe extendingfrom the heating drum for conveying products of combustion through thecompartment to be heated, said receiving compartment having an outletopening into said pipe, and said distributing compartment having a freshair inlet adjacent its lower end and outlets adj acent its upper end,said outlets opening into the compartment to be heated, and saiddistributing compartment surrounding the airreceiving com artment.

2. The com ination with a compartment to be heated, said compartmenthaving an outlet opening in the floor thereof; of a heater arrangedwithin said compartment and comprising a drum, an inner jacketsurrounding the drum and forming an airreceiving compartment, and anouter jacket surrounding the drum and forming an airdistributingcompartment, said receiving compartment having a plurality of openingsin the lower portion thereof, means for directing vitiated air from theopening in the floor of the compartment to be heated to said openings,and a heating pipe extending from the drum and through the compartmentto be heated, said pipe opening into the atmosphere surrounding saidcompartment and communicating with the air-receiving compartment,therebeing a series of outlet openings in the outer jacket for directingair therefrom and into the compartment to be heated, said outer jackethaving a fresh air inlet.

3. The combination with a closed compartment having an outlet opening inthe floor thereof and a receiving opening; of a heater comprising a drumextending over said receiving opening, a lamp suspended from and openinginto the drum, said lamp extending below the floor, an inner jacketsurrounding the drum and projecting into said opening, said projectingportion having inlet apertures, means for conveying air from the outletopening in the floor to the receiving opening, said means constituting aclosure for the space between the wall of the receiving opening and. thejacket, an outlet pipe communicating with the drum and the compartmentformed by the acket, and an outer jacket surrounding the inner jacketand constituting a closure for the receiving compartment, said outerjacket having a fresh air inlet, there being an outlet in the outerjacket for directing air into the closed compartment.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two Witnesses.

EDWARD B. RAYMOND.
